Goodman 20197308 Pressure Switch -.10" NO

The Goodman 20197308 is a genuine OEM air-proving pressure switch for the GMH950453BXAE gas furnace. Set to actuate at -0.10 in. water column and wired normally open (NO), it confirms the inducer draft is pulling correctly before the control board allows ignition — a core safety interlock that prevents firing without proper venting.

Specifications

  • Type: Negative-pressure draft-proving switch
  • Set point: -0.10 in. W.C.
  • Contact configuration: Normally Open (NO)
  • Fits: Goodman GMH950453BXAE and select furnaces
  • Equipment: Gas furnace
  • OEM Part Number: 20197308
  • Brand: Goodman (Amana compatible)

OEM vs. Generic

Set point accuracy is everything with a pressure switch. The OEM Goodman 20197308 is factory-calibrated to -.10" W.C. for the GMH950453BXAE, so it proves draft reliably without nuisance lockouts. Generic switches with an approximate set point are a common source of intermittent ignition failures. OEM is strongly recommended.

Install Difficulty: Easy

About 15 minutes. Cut power, note and transfer the two spade terminals, remove the mounting screws, and reconnect the hose to the correct port. Confirm the switch closes on a heat call after install.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GMH950453BXAE — 20197308?
Yes. This is the factory-specified OEM pressure switch for the Goodman GMH950453BXAE — 20197308. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch on my Goodman GMH950453BXAE — 20197308?
Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.
My furnace shows a pressure switch error. What do I replace?
Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.
Is this pressure switch compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman pressure switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
